Changelist

This PR contains my completed answers for Sprint 1 exercises on number systems.

The exercises cover understanding and working with:

  • Binary numbers
  • Hexadecimal numbers
  • ASCII encoding
  • RGB and grayscale colour representation
  • Bit-level data interpretation

I worked through the questions manually to strengthen my understanding of how number systems are represented and converted, focusing on learning the underlying concepts rather than using tools.

Questions

I don’t have any questions at the moment, but I would appreciate feedback on whether my explanations for number system conversions and byte interpretations are correct and clearly written.

You seemed to miss the last question in part 1, and I think you need to check Q23.

Comment thread number-systems/Part-1.md

Q6: What is 10001 + 10001?
Answer:
Answer: 10001 = 17 + 17 = 34 decimal = 100010 binary

This is one way of doing it, but what happens if you try just adding it in binary:
10001
+10001

???????

I missed that one. 0x21 hex will be 33 in decimal.
